In observance of next year’s Easter holiday, the Boston Athletic Association announced today that the B.A.A. 5K will be held on Saturday, April 19, rather than its traditional date, the Sunday before the Boston Marathon. Next year’s 118th Boston Marathon will be run one day after Easter Sunday on Monday, April 21, Patriots’ Day in the Commonwealth of Massachusetts.

In addition, the B.A.A. announced today that there will be a new course for next year’s B.A.A. 5K, starting and finishing in Boston Common rather than Copley Square Park, which has been the start and finish area since the race’s inception in 2009. The race will also be expanded to 10,000 entrants.

“We have expanded the field size for the 2014 B.A.A. 5K to provide more people with an opportunity to experience one of our athletic events during Boston Marathon Weekend,” said B.A.A. executive director Tom Grilk in a statement. “In doing so we are particularly mindful of the desire of a great many people to make an athletic display of their resilience in the face of the April 2013 attack on Boston.”

At the 2013 Boston Marathon on April 15, more than 200 spectators were injured and three killed after two bombs exploded close to the finish line on Boylston Street.

For 2014, the B.A.A. 5K start and finish line will be moved approximately .75 miles (1.2 kilometers) east to Boston Common. For the past two years, Boston Common has played host to the B.A.A. 10K in June.

“With an adjusted location and date, the B.A.A. 5K will continue to provide the boost of excitement and running spirit that have quickly made it a Boston Marathon Weekend tradition embraced by elite and recreational runners alike,” said Grilk.

The B.A.A. 5K course will still pass the iconic Boston Marathon finish line on Boylston Street.

Registration for the B.A.A. 5K will begin on Wednesday, February 5, 2014, at 10:00 a.m. EST on BAA.org, and will cost $50. The race is also the first leg of the three-race B.A.A. Distance Medley, a grand prix competition which also includes the B.A.A. 10K (June) and B.A.A. Half-Marathon (October). The man and woman registering the lowest overall total time for the three events wins $100,000.

In 2013, a race record of 5,649 athletes finished the B.A.A. 5K. Event records stand at 13:37 for men (Dejen Gebremeskel, 2013) and 15:12 for women (Werknesh Kidane, 2012).
